IMPROVEMENT "IN PLOW-COLTERS.

The Schedule referred to in these Letters Patent and making. part:v of the same;

' in the manner of attaching thesame to the plowbeam.

In order to'euable others skilled in the art to which my invention appertains to make and use the same, I will now proceed to describe its construction. and operati0u,referring to the annexed drawings, in which-e Figure 1 is a side elevation, and

Figure 2, a'front view of my colt-er, attached to a plow-beam.

A represents a, sleeve or tube, through which the' stem B of the colter passes.

The upper edge of the sleeve A is notched on its rear side,-and the stem Bis at its upper end provided with a. pin, a, which rests iusaid notch on the tube,

and thus secures the colter-to the sleeve, .but, at the same time, allows it to swing loose.

The lower end of the stem B is curved backward, and this end is forked, so as to allowthe colter to be piv oted within it.

The sleeve A is secured to the plow-beam D by means of two eye-bolts, E E, placed one on the upper and the other on the lower side of the plow-beam, the

sleeve passing through the eyes on said bolts.

On the opposite side of the plow-beamfrourthat on which the sleeve is placed the eye-bol tspass through a. plate, G, and are secured on the outside of said plate by means of nuts, H H, thus binding the sleeve firmly to the plow-beam. One, or, if desired, both of the bolts pass through slots iu'the plate G, allowing the colter to be attached to any sized plow-beam,

and, also, who adjusted more easily in any desiredposition without injury to the wood.

Although my device may be made of, any desired material, I prefer to make the sleeve of wrought iron,

which makes it light, neat, and cheaperthan any attachruent now in use.

' Havingthus fully described-my invention,

What I claim as new, and desire to secure by Letters Patent, is- The sleeve A, colter-stein B, eye-bolts E E, slotted plate G, and nuts H H, all constructed and combined, l

in the manner. and for the purpose set forth. In testimony that I claim the foregoing as my own, I aflix my signature in'presence of two witnesses.
